Did the salt test and it was low by 8%. Pushed the calibrate button and instantly was right on at 75%. Much much easier to calibrate than the Humi Care! More accurate too! Will definitely buy one for every humidor I own. At $12.95, it's a steal!

Calibration is easy, function is great, priced right, but like many other's in their reviews the diameter is too small to fit as a replacement for older analog mounted in humidor. They should really change their product description.

This product is vastly superior to a non-calibratiing analog. I have two and after calibrating them together I periodically put them in the same humidor. They have indicated the same reading every time. By having at least two and comparing them in this way, you can always know if they need recalibrating.

I had hoped to install it, as suggested, in the hole left when I removed the analog gauge that came with my small humidor. Unfortunately, it was too small to fit snugly into that hole, so I left the analog in and lay this one flat under the glass where I can read it. This means it is usually sitting on cigars, and probably not placed optimally. When I get around to building my own, larger humidor, I'll make sure it fits perfectly.

I bought one of these a couple years ago to put in a 4-drawer, glass front humidifier and have been very pleased with it ever since. It is easy to install, easy to read, and quite accurate. So when I saw it on sale recently, I bought 2 more, one for each of my smaller humidifiers so I can be sure of where my RH is at all times in all 3 of my humidifiers. I am now pondering buying 1 or 2 more to put in my Taylor guitar cases. I love living in Colorado, but the very dry climate makes humidifying cigars & guitars a REALLY big deal, and this hydrometer is the best way to make sure you are doing it right!

This is a great unit. It responds fast to the temperature and humidity. Is easy to calibrate. It will not fit in the drilled hole in my humidor - too small in diameter. It does have a peel and stick magnetic mount included.

I bought 2 of these for the price most online retailers were selling one. Threw one in my 2 level humidor and noticed a significant RH difference between the Xikar and the digital unit that came with my box. I threw both Xikars and my digital humidor in bag and did a calibration test. Turns out the XIkars were both dead on and my digital unit was off by 18!! Xikars in, my digital in the trash.

I TRIED a Humi-Care from Cigars International and it was a major piece of junk. Impossible to calibrate.(wrote a review on CI's website about their Humi-Care piece of junk and they did not even post it, LMAO) This one is very easy to calibrate. Push the calibrate button and you are done it is that simple. Very accurate, it read the same in a salt test and in a Boveda calibation bag.

I bought a humidor from Thompson and they hygrometer was garbage. It would fluctuate so much that I knew it was poor. This hygrometer seems to be accurate. The display is very easy to read and it reads temperature as well. I really enjoy my cigars and want to keep them fresh. My sticks are in great shape now and this new hygrometer gives me piece of mind knowing that my humidor is doing its job.

I purchased this because it can be calibrated, and the build-in hygrometer on my humidor seemed to be reading too low, based on how my cigars felt. First thing I when I got the new Xikar was calibrate it with the salt test. It was within one point of perfect. When I put it into the humidor, sure enough it read four points higher than the built in. I thought I must have done something wrong, so I re-calibrated the Xikar, and again, it was within one point of perfect (75%rh). This allowed me to adjust my humidity level with confidence, and now my cigars aren't mushy!
